GEORGE STYLES, OF NEW YORK,` N. Y.

IMPROVEMENT IN UIVIBRELLAS.

Specification forming part of Letters Patent No. 53,702, dated April 3,1866.

To all lwhom 'it may concern Be it known that I, GEORGE STYLES, of thecity, county, and State of New York, have invented a new and usefulImprovementin Parasols, 85e.; and I do hereby declare that theiol lowingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, forming part of this specicaion, in which-Figure l represents a longitudinal central section of this inventionwhen the sameis open and ready for use. Fig. 2 is a detached sectionalview of a portion ofthe staff. Fig. 3 is a transverse section of thesame, taken in the plane indicated by the line x a', Fig. l.

Similar letters of reference indicate like parts.

This invention relates to a parasol the staff of which is constructed onthe telescope principie, so that the same can be len gthened when theparasol is to be used and shortened when theparasol is not used.Theinner or extension tube is slotted throughout a large portion of itslength, and a pin passing transversely through it, and secured iii theouter or main tube, prevents the same from turning round,

and a suitable spring-catch attached to the runner drops into holes inthe outer and inner tubes and locks the parasol both when the' same isopen and when it is closed.

A represents the staff of my parasol, which is constructed of an outertube, a., and an inner tube, b. To the top end of the outer tube a ring,c, is firmly secured, which sustains the wire that forms the bearingsfor the ends oi" the ribs d in the ordinary manner, and a runner, e,slides up and down on said outer tube, which sustains a wire, j', thatforms the bearings for the braces g.

The tube b is fitted in the tube a., and it is provided with a slot, h,through which a pin, fi, passes, that is secured in the outer tube, a,so that said inner tube can be drawn in or out to the extent of theslot; butit is not allowed to turn in the main tube. A handle, B,secured to the inner tube, b, serves to operate the same and to hold theparasol when the same is to be used. This handle is provided with anannular socket to admit the lower end of the main tube a, so that thelength of the statt' can be reduced as much as possible when the parasolis not used.

The ruimer e is provided with a springcatch, j, which diops into aliole,7c, in the outer tube and over the end of the inner tube when theparasol is open, and into holes lm in the outer and inner tubes when theparasol is closed, and by these means said parasol is locked when it isopen as well as when it is closed. p

The spring-catch j consists of a pin which is supported by atrigger-spring, n, and guided in the runner. By pressing against thecurved part of the trigger-spring the pin is released from the socket inthe ruimer and from the holes in the tubes, and the para-sol can beopened or closed, as the case may be.

By this arrangement a simple and durable parasol is obtained, the statt'of which can be readily lengthened or shortened, and which whenshortened is convenient to carry in a hatbox or other small receptacle.

What I claim as new, and desire to secure by Letters Patent, is-

1. The telescope-tubes a b, with holes k Z m, in combination with thespring-catchy' and runner e of a parasol, constructed and operatingsubstantially as and for the purpose described.

2. The trigger-springn, in combination with the catch j, ruimer c, andtubes a b, substantially as and for the purpose set forth.

The above specification of my invention signed by me this 14th dayotSeptember, 1865.

GEORGE STYLES.
